They are widely used in high-rise buildings, super high-rise building frames, and other building structural systems. The bond-slip performance at its dual interfaces, i.e., the steel tube-outer concrete interface and the steel tube-core concrete interface, critically controls the load transfer efficiency and overall structural behaviour of such members. This review comprehensively overviews recent research on bond-slip performance at CE-CFST interfaces, focusing on experimental methods, influencing factors, bond strength prediction models, and bond stress-slip constitutive relationships for both interface types. It further analyzes the synergistic load-transfer mechanism between the dual interfaces and the effects of interface degradation on stress redistribution and the overall load-transfer path, and discusses the applicability and limitations of CFST interface theories in the dual-interface system of CE-CFST members. Finally, future research directions are proposed, including conducting coupled multi-factor analyses, developing high-precision bond strength prediction methods, refining bond stress-slip constitutive models, and promoting the application of intelligent monitoring technologies for interface damage identification. This review aims to provide references for the design and building engineering application of CE-CFST structures.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"35 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In TCC members, shear connectors transfer interface shear and restrict slip between the timber and concrete layers. Fibre-reinforced polymer (FRP) connectors have recently emerged as a lightweight, corrosion-resistant alternative to conventional steel fasteners; however, experimental evidence on their flexural performance within TCC applications remains scarce. This study evaluates the flexural performance of CLT-concrete composite beams incorporating six types of shear connections: SFS Intec screws (SFS), perforated steel plate (PSP), carbon and glass FRP rods (CR and GR), and T-shaped CFRP and GFRP plates (CP and GP). The beams were designed to transfer loads solely through the shear connectors, with a plastic sheet placed between the timber and concrete to eliminate direct interfacial bonding and friction. Four-point bending tests showed that FRP connectors can enhance composite action, bending stiffness, and bending capacity. Among the tested specimens, the GR connection achieved a higher capacity than the SFS connection, whereas the CR connection exhibited a lower value. In addition, both CP and GP connections achieved higher average maximum loads than the PSP connection. Analytical predictions of stiffness and bending capacity, based on partial composite action theory, showed reasonable agreement with the experimental results, supporting the applicability of the γ-method and Timoshenko beam theory to the tested beam configurations. Overall, this study provides an evaluation of FRP connections in TCC members, offering critical evidence to support their broader adoption in structures.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"268 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prototype structure was a 120-m, 40-story, three-bay PCSW structure in the region of seismic intensity VII, with the bottom three stories serving as the experimental substructure. To account for the effect of the upper structure’s overturning moment, a variable axial force loading system was designed to apply vertical forces to the experimental substructure. The pseudo-dynamic test was performed under eight sequential earthquake excitation levels with peak ground accelerations (PGAs) ranging from 35 to 620 gal. Experimental results showed that the plastic hinge first formed at the coupling beam ends on the 8th, 13th, and 16th stories under the 100-gal excitation. The hysteresis curves of the experimental substructure were nearly linear at the PGAs of 35 gal–220 gal. Under the 620-gal earthquake, the experimental substructure maintained approximately 65% of its initial stiffness, and the yielding of the vertical reinforcements in the shear walls was first observed. The displacement response of the prototype structure was governed by the first vibration mode, and the maximum drift ratio occurred between stories 12 and 15. The peak drift ratios were 1/1609 and 1/208, corresponding to the frequent (35 gal) and rare (220 gal) earthquake excitations. These values are below the limits of 1/1000 and 1/120 specified in GB 50011-2016. This demonstrated that the 120 m high-rise PCSW structure with GCMD connections had reliable seismic performance, making it applicable in regions with seismic intensity VII.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"40 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
